    最好后台有针对手机版的做一个压缩。压缩成几个档位。
    安卓手机firefox出现过视频mesh不可见或者闪烁的情况。
    
    
    视频最容易导致崩溃， 模型还好
    
    数据速率为4064kbps，1920*1080px  时测试部门电脑崩溃
    数据速率为1824kbps，720 *576px   时正常
    所以尽量降到2000以下 同时播放个数最好不超过2个 可能需要将src归零  并延迟加载、不自动播放
    
    
    
    
    有遇到某张图在ios里显示不出，但在ps重新输出后就可以。这张图的dpi高达500，不知道是否与此有关。
    遇到过ios14.8.1、14.7.1 无法播放webm(来自1050)。 onloadedmetadata失败
